RELATIVE STOCK PRICES AND THE FIRM SIZE EFFECT

A stock's relative price ratio, defined as the ratio of the current price to the average of the highest and lowest prices over some holding period, is shown to be a better predictor of future stock returns than firm size. The price ratio has an even stronger January seasonality than does firm size. After controlling for price ratio variations, firm size has no significant relationship to return. The abnormal returns for the price ratio effect are consistent with those predicted by optimal tax selling considerations.     

THE CONTRIBUTION OF INFLATION UNCERTAINTY TO THE VARIABLE IMPACTS OF MONEY ON STOCK PRICES

This paper examines the effects of inflation uncertainty on the lag structure between money growth and stock prices. Using a varying parameter model and the Livingston survey data 1 1 Livingston, J. A., “Inflation Expectations Surveys.” Published twice annually, Philadelphia Sunday Bulletin (1948–1971), Philadelphia Inquirer (1972 on).
as a proxy for inflation uncertainty, the results suggest that only current money growth influences stock prices. However, a large percentage of this positive impact can be expected to be offset by inflation uncertainty prevailing at the time.     

DEREGULATION AND THE VOLATILITY OF UK STOCK PRICES

This paper examines the behaviour of the UK stock market for significant changes in volatility over the four years surrounding Big Bang i.e. 27 October, 1986 when the market was substantially deregulated. The main findings are that after Big Bang but prior to Black Monday, the UK stock market was no more volatile than prior to Big Bang, but that after Black Monday, the UK market was more volatile than prior to Big Bang even after adjusting for increases in global volatility.     

THE EFFECT OF U.S. TRADE DEFICIT ANNOUNCEMENTS ON THE STOCK PRICES OF U.S. AND JAPANESE AUTOMAKERS

The existing literature on the trade news effect on asset prices generally looks at exchange rates and stock market indexes. We focus on individual stocks: the U.S. and Japanese “Big Three” automobile stocks. We examine Japanese automobile American Depositary Receipts (ADRs), not the stocks per se, to avoid the time lag problem. First, we find deficit news shocks, especially the positive shocks, have a negative effect on the Japanese automobile ADRs. Second, we find only weak evidence that the news effect is different under different economic conditions. Third, trade news is found to be a competitive shock to the automakers in the sense of Karolyi and Stulz (1996) . Last, statistically generated U.S.–Japan bilateral trade deficit news and bilateral auto trade deficit news have no effect on the automobile stock in general.     

THE ADJUSTMENT OF STOCK PRICES TO COMPLETELY UNANTICIPATED EVENTS

This paper utilizes standard cumulative residual analysis to study the response of stock prices to completely unanticipated events—fatal commercial airline crashes. Results indicate that the immediate negative reaction to fatal airline crashes is significant for only one full trading day after the event occurs. Hence, the market appears to assimilate the new information rapidly, even if the crash occurs in a remote geographic location. The paper also considers market response after the initial reaction period by assuming that the actual cumulative average residuals are drawn from the same distribution as the pre-crash base period and by calculating the probabilities that observed changes would occur. Results provide no evidence that underreaction or overreaction appeared in the initial response period. The hypothesis of complete, immediate adjustment is also supported by a repetition of the analysis on the subsample of airplane crashes where the greatest potential loss occurs.
